This will be used as the Master tracking ticket for issues reported involving the update to 1.9.0 causing other mods to throw exceptions because they don't like the Resplendent Prism's code requesting the max stack size of their items to build its blacklist.

This may or may not occur with NEI installed. As neither AS nor AS+NEI crashes on their own, and NEI has confirmed this has no involvement on them (TheCBProject/NotEnoughItems#162), if you have none of the below mods installed in your pack you will need to investigate to determine based on installation or stack trace what mod is throwing an exception when queried, and open a ticket once that is done. Please update this thread by posting into it when you do so, and I'll attempt to track it for ease of reference, along with updates pushed to resolve the ticket when yours closes.

If it's referencing NEI in the crashlog, attempt to start it without NEI and see if that functions as a work-around. You will still need to open a ticket on the other mod's bug tracker (Not AS, not NEI, the OTHER mod).

Issue resolved in:
Ancient Warfare - Fixed in 1.12.2-2.6.1.251
Mekanism/Mek Generators - Fixed in 9.4.12.348
IC2 - Fixed in IC2 2.8.85
VanillaFoodPantry - Should be fixed in 4.2.1. Wabbit0101/mods_hoardercraft#47
Custom NPCS - Fixed in (07jul18) release.
Erebus - vadis365/TheErebus#624 FIXED IN NEXT RELEASE AS OF JULY 25TH NOTIFICATION.
Unique Crops archived their ticket, claiming no longer an issue with newest versions of both.
YABBA issue closed.

Issue still present in:
Lucraft Core
Advanced Rocketry versions prior to 1.4.0-84-universal.
Ender IO - Conflicting reports. Some users are launching with EIO without issues, likely an undetermined interaction trigger.

ALSO REMOVE SPONGE AND TEST THAT WAY. Not supported by AS to begin with as it breaks a considerable number of things in the mod because of how things are modified by Sponge.

Is the Custom NPCs issue not related to this one too?

#755
Custom NPCs - Curse Issue Tracker

I just forgot it because made this without enough caffeine in my system yet.

I looked through my mods folder and did not see sponge's .jar at all, but looking in my log I saw that Malisis core mentions org.spongepowered. So I removed Malisiscore and Malisisdoors, and the issue persisted.

I also tried removing IC2 at the same time, with no luck.

Here is my latest log file

@MrFastZombie That log is a disaster of errors, and even forge is having problems in it. Pull forge up to at least 2705 (recommended) and try again. If it still fails, you're going to have to use a binary method of determining what's causing it to narrow it down.

In my case it seems to be caused by erebus, the weird thing is the exception SEEMS to be getting thrown by instantiating an item stack of vanilla bowls, which makes no sense at all

@kotoroshinoto I have Erebus 1.0.22 and it works fine with AS 1.9.0 - my hidden culprit is Custom NPCs which leads to the crash log refering to different other mods like Tinker and IC2.

It seems in my case, Advanced Rocketry 1.4.0-67 was causing the crash. I updated it to 1.4.0-85-universal, and it works fine now.

EDIT: It's 1.4.0-84-universal. Made a typo.

This is the crash i got that pointed to EIO
& only occured with AS 1.9 https://gist.github.com/Morpheus1101/230f3911e36bceb5b51c2ad623c13242

Please report on the EIO tracker.

I have enderio, but the problem primarily was coming from erebus. I still have enderio right now after removing erebus and it isn't experiencing this crash.

@kotoroshinoto Which Version of erebus do you use?
I load up a modlist of my pack soon that don't crash. I removed NPC-Integration and Custom NPCs and can confirm that 'Integration isn't the culprit because the Issue persist with the same crash log when I only remove NPC-Integration.

My actual modlist with versions that loads correctly:
https://gist.github.com/Deloyar81/9a2849310d510c246ec05b9974bf060f

With the crashes i have received 2 times, EnderIO and CyberWare have both been mentioned an di have quite a few of the mods listed in the First Post

Should remove the ones in the first post and test again, of upgrade to fixed versions where listed. It's been confirmed CyberWare isn't the culprit for that one, it's just getting pointed to for the fault. Haven't had a report on EIO yet.

"Advanced Rocketry versions prior to 1.4.0-85-universal"

i'm on 1.12.2, and 1.4.0-84 is the newest version available.

removing erebus stopped the issue for me, for now

this currently doesn't show the version of erebus as I removed it, but it SHOULD show everything else i am using. (erebus was the only thing I've removed.)

Ah, alrighty dokey. good luck with them all.

So, it seems the startup crash with Unique Crops was partially fixed with 1.9.2.

It no longer occurs if just Astral Sorcery & Unique Crops are installed together... however, I am still experiencing the crash when NEI is installed also:
https://paste.dimdev.org/uvazurizic.mccrash

I removed NEI, and experienced the crash with AS 1.9.2 + UC + Cyberware as well:
https://paste.dimdev.org/cevezineri.mccrash

No, would need to either remove the mod throwing the exception when asked for stack size, or revert to a Pre-1.9.x version of AS. Please test with 1.9.2 installed if you've not yet, to see if there are improvements.

I'm very sorry to ask, is there an option or ability to disable the 'Resplendent Prism' (and thud the check) in the configs or via a customisation mod?

Not an ideal request, but i realize some mod authors are singular people who don't release often, and can't downgrade.

Edit: Cheers @Doomgull for the fast reply and confirmation. Looking forward to 1.9.2, looking at rolling one particular mod cNPCs back to Dec'17 (via 9minecraft unfortunately) as it doesn't seem to have issues, and testing against world stability. Thanks again for your reply, and your work on AS!

Moving above to here from #780

Im having the same error with Giacomo's Foundry but i can't seem to find an issue page for the mod.

@AdaraChristine that looks like the issue Hubry just referenced from YABBA, actually. Rolling back to YABBA version 1.1.2.10 should resolve it.

Thank you, it worked and i can run the latest version. :)

Custom NPC's update (07jul18) solves the issue (for me).

@generrosity check new CustomNPCs release mentioned in Deloyar's comment

Working indeed - cheers @Deloyar81 and for your patience with conflicts Doomgull etc. Noppes put a few quick versions through via his Discord (latest 09jul18 looks to be final upload for a while).

Erebus in that stack with issues still from above. If MoreCommands is in there (on mobile) try cutting it to see if it repeats the HowlingMoon issue.

MoreCommands is not in that pack. I'm trying to deduce the Howling Moon issue via the additive approach, add until it errors

I feel like Howling Moon may have some issues with Astral Sorcery. You might want to check to be certain.

I'm archiving this now. Major offenders have tracked resolutions. Anything else comes up or there's a Lucraft response, it'll need a fresh ticket anyhow.
